ICE3A1565

Product Summary

The ICE3A1565 is an off-line SMPS current mode controller with integrated 650V startup cell/CoolMOS. The new generation CoolSET TM-F3 provides Active Burst Mode to reach the lowest Standby Power Requirements <100mW at no load. As the controller of the ICE3A1565 is always active during Active Burst Mode, there is an immediate response on load jumps without any black out in the SMPS. In Active Burst Mode the ripple of the output voltage of the ICE3A1565 can be reduced <1%. Furthermore, to increase the robustness and safety of the system, the device enters into Auto Restart Mode in the cases of Overtemperature, VCC Overvoltage, Output Open Loop or Overload and VCC Undervoltage. By means of the internal precise peak current limitation of the ICE3A1565, the dimension of the transformer and the secondary diode can be lowered which leads to more cost efficiency. An adjustable blanking window prevents the IC from entering Auto Restart or Active Burst Mode unintentionally during high load jumps. The CoolSET TM-F3 family consists a wide power class range of products for various applications.
